Those instructions will most likely not work. The whitelight version is very new (first post is only a month old), and people have just barely started hacking it yet. I think only the information found in this forum is valid so far (and people are suggesting things that don't work half the time). Following instructions for the blue light might be risky, and you might end up with a bricked unit.

Wait until everything is streamlined and you find updated wiki pages targeting the white light specifically.
